Genetic variability and heritability are useful parameters that can help the breeding during different stages of crop improvement. The success of such programme will largely depend on the extents of genetic variability available in the base population and heritability of the characters under improvement. Therefore, a clear understanding of genetic parameters is of paramount importance to develop a breeding strategy.Proper exploitation of variability in a crop like sugarcane with a complex ploidy and a high level of heterozygosity is a complicated process.The study was undertaken to determine the potential of poly crosses and station cross in sugarcane, obtained by pollinating the female parents Co 94012, Co8371, 86V46 and Co 7201 × Co 99006to generate variants for eight traits and frequency distribution pattern of variants, hence generated. 642 seedlings raised from three poly crosses and one station cross, comprising high sugared commercial varieties were investigated.Left skewed distribution (Skewness<0) was observed in all crosses, thereby indicating that most values are concentrated on the right of the mean. Leptokurtic distributions in progeny of PCII and PC III derived from Co 8371 and 86V46 PC, inferred that distribution of progeny presented higher peaks around the mean compared to normal distributions, which leads to thick tails on both sides. This signified that the most of the seedlings from Co 8371 and Co 94012 performed superior to the population mean.
